Currently, the Korean Pharmacopoeia (KP XI) recommends HPLC and potentiometric titration (which is less specific than HPLC) for the determination of triflusal content in capsules and raw materials, respectively. Additionally, the British Pharmacopoeia (BP 2017) and European Pharmacopoeia (EP 8.0), which include a monograph for triflusal in raw materials only, describe a titration method for the assay. The latest version of the United States Pharmacopoeia (USP 39) and Japanese Pharmacopoeia (JP 17) still have not published monographs for triflusal and its preparations. To improve the specificity and efficacy of the assay, we present an HPLC method to determine triflusal content in both raw materials and capsules. The proposed method was validated in accordance with the requirements of the International Conference on Harmonization. A good linear relationship was achieved for triflusal in the range of 200-1250 μg/mL with a coefficient of determination of approximately 0.9996. The relative standard deviations (RSDs) of inter- and intraday precision were 0.73-1.12 % and 0.34-0.51 %, respectively. The recovery percentage of triflusal was in the range of 98.80–101.31 %. Because its system suitability, intermediate precision, and robustness were satisfactory, this method could be suitable for determining triflusal content in raw materials and capsules.
